慢性肾功能衰竭(下称慢性肾衰)常伴发心脏损害,心律失常是心脏损害的一种表现,严重心律失常是导致死亡的主要原因之一.现将我院1989年3月至1991年12月收治的72例既往无心脏病史的慢性肾衰患者,就其心律失常进行分析.临床资料本组72例,男41例,女31例,年龄15～82岁,其中40岁以下38例,40岁以上34例.原发病为慢性肾炎59例,多囊肾7例,慢性肾盂肾炎4例,狼疮性肾炎及双输尿管狭窄各1例.主要检查结果:血尿素氮21.3～92.9mmol/1,平均40.8mmol/1,其中≥28.6mmol/1者64例.二氧化碳结合力2.8～25.4mmol/1,其中≤16mmol/1者42例,正常范围者30例.血清钾2.07～8.25mmol/1,其中<3.5mmol/1者24例,高于5.2mmol/1者10例.均有不同程度的贫血,其中Hb≤60g/1者39例.血压正常者10例,收缩压≥22kPa者46例, Chronic renal failure (hereinafter referred to as chronic renal failure) often associated with heart damage, arrhythmia is a manifestation of heart damage, severe arrhythmia is one of the leading cause of death is now our hospital from March 1989 to 1991 72 cases of patients with chronic renal failure who had no history of heart disease in December were analyzed in their arrhythmia.Clinical data The group of 72 patients, 41 males and 31 females, aged 15 to 82 years, of whom 38 under 40 years of age , 34 cases over the age of 40. The primary disease was chronic nephritis in 59 cases, 7 cases of polycystic kidney disease, chronic pyelonephritis in 4 cases, lupus nephritis and ureteral stricture in 1 case.The main test results: blood urea nitrogen 21.3 ~ 92.9mmol / 1, with an average of 40.8mmol / 1, of which ≥ 28.6mmol / 1 in 64 cases.Carbon dioxide binding power of 2.8 ~ 25.4mmol / 1, of which ≤16mmol / 1 in 42 cases, the normal range of 30. Serum potassium 2.07 ~ 8.25mmol / 1, of which <3.5mmol / 1 in 24 cases, higher than 5.2mmol / 1 in 10. There are varying degrees of anemia, including Hb ≤ 60g / 1 in 39. Normal blood pressure in 10 cases, systolic blood pressure ≥ 22kPa 46 cases,
